This is a type used in Stencila Schema for describing an upstream execution dependency of a node.

It exists to make the inputs and prerequisites of executable nodes explicit in the schema, enabling incremental execution, invalidation, and inspection of execution graphs.

Key properties identify the dependency node and the relation that explains why it is required.

Analogues

The following external types, elements, or nodes are similar to a ExecutionDependency:

build dependency edge: Close graph-theoretic analogue for an upstream dependency relation between executable units, though Stencila also records node identity and code location metadata.
